Definition
The knowledge derived from DATA.
Term
What factors have contributed to the growth of digital data?
Four answers.
Definition
  1.  An increase in data-processing capabilities.
  2.  The lower cost of digital storage.
  3. Affordable and faster  communication technology.
  4. The proliferation of applications and smart devices.

 

Term
Structured Data
Definition
Organized in rows and columns in a rigedly defined format so that application can retrieve and proccess it efficiently.
Typically stored using a DBMS.
Term
DBMS
Definition
Database Management System
Term
Unstructured Data
Definition

Data is unstructured if it's elements cannot be stored in rows and columns.

Examples: Costumer contacts can be stored as sticky notes, e-mail messages, business cards or .doc/.txt/.pdf digital formats.

Term
Big Data
Definition
Data sets whose sizes are beyond the capability of commonly used software tools to capture, store, manage and process within acceptable time limits.
Term
MPP
Definition
Massively Parallel Processing
Term
Data Science
Definition
The synthesis of several existing disciplines, such as statistics, math, data visualization and computer science to enable data scientists to develop advanced algorithms for the purpose of analyzing vast amounts of information to drive new value and make more data-driven decisions.
Term
Storage Devices
Definition
Devices designed for storing data.
Term
Server-Centric Storage Architecture
Definition
Open System in which the storage is internal to the server, and can not be shared with other servers.
Term
Information Centric Storage Architecture
Definition
Storage devices are managed centrally and independent of servers.  These storage devices are shared with multiple servers.
Term

What are the Characteristics of Storage Systems?

Seven answers.

Definition
  1. Availability
  2. Security
  3. Capacity
  4. Scalability
  5. Performance
  6. Data Integrity
  7. Manageability
Term
Data Center Characteristic - Availability
Definition
A data center should ensure the availability of information when required.  Unavailability of information could cost millions of dollars per hour to businesses.
Term
Data Center Characteristic - Security
Definition
Data centers must establish security policies, procedures, and core element integration to prevent unauthorized access to information.
Term
Data Center Characteristic - Capacity
Definition
Data center operations required adequate resources to store and process large amounts of data efficiently.  What capacity requirements increase, the data center must provide additional capacity without interrupting availability or with minimal disruption.
Term
Data Center Characteristic - Scalability
Definition
Business growth often requires deploying more servers, new applications and additional databases.  Data center resources should scale based on requirements, without interrupting business operations.
Term
Data Center Characteristic - Performance
Definition
All the elements of the data center should provide optimal performance based on the required service levels.
Term
Data Center Characteristic - Data Integrity
Definition
Data integrity refers to mechanisms, such as error correction codes or parity bits, which ensure that data is stored and retrieved exactly as it was received.
Term
Data Center Characteristic - Manageability
Definition
A data center should provide easy and integrated management of all it's elements.  Manageability can be achieved through automation and reduction of human, or manual intervention in common tasks.
Term

What are the key Management Activities for a Data Center ?

Three Answers

Definition
  1. Monitoring
  2. Reporting
  3. Provisioning
Term
Data Center Task - Monitoring
Definition
A continues process of gathering information on various elements and services running in a data center.
Term
Data Center Task - Reporting
Definition
Reporting is done periodicalyy on resource performance, capacity and utilization.  Reporting tasks help to establish business justifications and chargeback of costs associated with data center operations.
Term
Data Center Task - Provisioning
Definition
Provisioning is a process of providing the hardware, software and other resources required to run a data center.  Provisioning activities primarily include resources management to meet capacity, availability, performance and security requirements.
Term
Virtualization
Definition
A technique of abstracting physical resources, and making them appear as logical resources.
Term
Cloud Computing
Definition
Enables individuals or business to use IT resources as a service over the network.
